King, clad in a red-and-white combo with matching kicks, looked as relaxed as ever during the flight. "Flyer than ur kid," Tyga wrote over the Snapchat pic of his stylish son, whom he shares with Rob Kardashian's fiancé, Blac Chyna.

Meanwhile in Los Angeles, Kylie's sisters, Kendall Jenner and Kim Kardashian West, were having a little trouble with their transportation while heading to Kanye West's "Famous" exhibition. Kim claimed that Uber, a popular car service app, had banned Kendall.

"Ugh I have to drive @KendallJenner around tonight bc she's banned from Uber!" the Selfish author tweeted. "Why @Uber?!?! She's a "model" passenger!!!!!"

On Saturday, however, an Uber source confirmed to ET that Kendall "has not been banned."
